ARTIFICIAL SEA-WATER. 267 



the Glasgow Meeting of the British Association in 

 1855. 



It is scarcely necessary to add, that, if you can 

 conveniently procure water from the sea, you should 

 do so by preference ; " si non, Ms utere meciim.^^ 



I am glad to fortify my own statements of the 

 perfect success of this Artificial Sea-water, by the ex- 

 perience of Mr. W. A. Lloydj who, by his extensive 

 and rapidly-increasing business of supplying stocked 

 Aquaria to every part of England, is well qualified to 

 express a judgment. Mr, Lloyd for a long time never 

 used any other tcater tTian this co7nposition.'^ The 

 results of his observations were communicated to the 

 Microscopical Journal for July, 1855, in the following 

 paper, which, as it bears not only on the question of 

 water, but on the general subject of this volume, I 

 shall, with the permission of the author, quote entire. 



" Memoranda on the employment of Artificial Sea- 

 water in Marine Aquaria. 



''Early in the summer of last year I commenced 

 some experiments on artificial sea-water, made ac- 

 cording to the formula proposed by Mr. P. H. Gosse ; 

 the ingi'edients, in the proper proportions, having 

 been procured from Mr. William Bolton, 146, Holborn 

 Bars, London. In it I have successfully maintained 

 alive the following marine productions : — 



AXIMALS. 2 Hydractinia echinata. 



Zoophytes. 3 Actiniamesemhryanthe- 



1 Clava multicornis. mum. 



* He now supplies real sea-water, as well as artificial, according 

 to the wishes of his customers.
